Electricity storage solution for the grid

Impetus

Alevo, based in (1920*) Martigny, Switzerland has two products at the forefront of technology in the electricity storage market:

1) Containerised batteries (not unlike the container based computer server systems used by Google and others). The battery storage replaces the need for spinning reserve and performs peak shaving and time shifting. Containers are infinitely scalable and can be located in places of need and easily moved. Standard 40 “foot” units. The batteries use inorganic lithium which is non-inflammable, fully dischargeable, no heat problems, and suffers no calendric aging. So far they have achieved 20 years of use in terms of cycles and are continuing to test to find the breaking point.

2) Alevo Analytics is a computer software system that can evaluate the location placement, megawatt sizing and energy services (eg frequency regulation and voltage support) mix to optimise the placement of the battery container units at various points within the grid.

While battery technologies will change over time, the basic concept of containerisation and analytics software will remain in demand - particularly as renewable energy systems form a larger portion of a nation’s power supply. Not surprisingly, their first system was sold to China (Guangdong). The company is offshoring the manufacture of the system to a plant it has created in the US, recycling a building that was used as a cigarette factory.

Typical Swiss.

*I give the postcode, because anyone familiar with the Swiss postcode system can guess the approximate location of this small town using the numbers (eg 1950 Sion) is just down the road, as is 1200 Geneva. Unlike the stupid, complex, expensive, Eircode “system” being imposed on Ireland by an incompetent, self-centred, smug, over pensioned “public service” that invariably puts two fingers up to the general needs of the economy and the population as a whole. Eircode will tell you almost nothing because it is encrypted, long, complex and a breach of privacy in the hands of hackers and big data users.

Typical Oirish.

Give this is a battery and has no rotational inertia

Ireland has a requirement to maintain at least 50% of its supply from high inertia generators for voltage and frequency stability

I wonder what happens as more inverter type generators come onto the network

They get curtailed and in most cases they get the SMP or CMP and put up the price of electricity.

They are currently looking at upping the SNSP to about 70%

The what to the where now ?
